SELF-LOADING PISTOL.

To @ZZ whomy t may concern.:

Be it known that I, HEINRICH Onrems, manufacturer, citizen of the German Republic, residing at No. Cyriakstrasse, in the city of Erfurt, Germany, have invented certain new and useful Improvements in Self-Loading Pistols, (for which I have filed applications in Germany, July 3, 1916, Patent No. 307,635, Austria, May 25, 1917, and Hungary, June 23, 1917,) of which the iollowing is a specification.

The present invention relates to improved means Jfor securing the barrels of automatic pistols, according to which the barrel is provided with a specially-constructed stud for engagement in a hole in the handle. With the known arrangements of this kind it is necessary for securely fixing the barrel, to employ a separate bar, which is inserted into agroove Jformed partly .in the breech and partly in the barrel; this is both tedious and expensive. It is the object of the present invention to obviate this drawbackand to ensure an absolutely rigid it of the barrel. For this purpose the stud on the barrel is provided, according to the present invention, with lateral extensions, which after the Astud has been introduced into the hole 1n the handle, and the barrel has been swung around will engage'with corresponding enlargements of the stud hole.

In the drawing a constructional form of this arrangement for securing the barrel is exemplified on an automatic pistol with a breech sliding on the handle'and enclosing the barrel.

Fig. 1 is a side view. Fig. 2 is a top view of' the pistol with the breech partly broken away. F 3 is a top view of the front part of the handle. Fig. 4t is a side view of the rear part of the barrel and Fig. 5 is a bottom View of the same.

The general arrangement of the pistol shown is of the known kind. At the rear lower end of the barrel is provided a stud b,

which has two lateral extensions or wings c Specification of Letters Patent.

and al. Corresponding to the shape of this stud a hole or recess f is provided in the handle e; this recess is undercut and has two enlargements through whichl the extensions c and Z of the stud may enter when the barrel is held at right angles to the axis of the pistol, as shown by dotted lines in F ig. 2. YVhen, therefore, the breech g has been removed, the barrel may be readily removed by turning 'it in the manner described, and it may be refitted in a similar manner; when swung into axial position, it will be then locked to the handle with the known bayonet lock.

The character of this lock allows of di? mensioning the engaging parts in such a manner that they will have a great strength. rPhe correct position of the barrel relative to the handle is ensured by a stop z, `which engages in a recess z' provided on one side The engag ing parts arev so made that when the barrel is moved into its normal position, a strongl clamping` effect is produced, which may how; ever, be easily overcome as the barrel is employed as a lever.

What I claim to secure by Letters Patent of the United States is Improvement for securing the barrel of selfioading pistols consisting of a stud onk the breech end of the barrel and at right angles thereto, said stud having lateral eX- tensions, in the handle a recess of corresponding sha-pe and undercut to receive said winged stud when the barrel is held at right angles to its normal position, and to hold said barrel, when swung into normal position.

In testimony whereof I aix my signature.
